Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009836, here are decompositions:

17 + 1009819 = 1009836
29 + 1009807 = 1009836
89 + 1009747 = 1009836
109 + 1009727 = 1009836
167 + 1009669 = 1009836
193 + 1009643 = 1009836
199 + 1009637 = 1009836
227 + 1009609 = 1009836

Showing the first eight; more decompositions exist.
